Update...Friday evening while cutting some flowers for the wife, a beautiful, pristine and very large female flew into the yard, popped an egg on a common MW and flew away. I figured that finally, they had found waystation 2638. Well, it appears that at least here in Massachusetts, the repopulation is a success. At about 12pm yesterday afternoon, I went into the backyard to get some boat wax and there was not one, not two, but three very large and again, very pristine, females on various milkweeds. They visited throughout the afternoon. I collected over 60 eggs from common, swamp and purple MW! Combine those with the wild patches that I went to on Saturday and I have over 24 cats and 85 eggs! In my first week of the collection and rearing season, I have 109 eggs and cats total! At this same time last year, I had 12 chrysalis only.
Looks like it is going to be a very big year for population recovery, at least in the NorthEast...I hope.
